When the checkCombo, everything seems to be fine. The two selected entries are displayed in the combo, seperated by ','. But when I click to open it, no checkbox is checked.
When I put a breakpoint on your "selectionChange" listener, I see a list (without the "All" entry) with my two values checked.

I don't really have time for now to investigate, so I report it now.
If I find something, I'll tell you.

Maybe the id field in your store is not a string but integer so you have to set it like this [1, 2, 3]?
